Waves are disturbances that carry energy through a medium from "summary" of The World of Physics 2nd Edition by John Avison
Waves are a fundamental aspect of physics, representing disturbances that propagate through a medium. These disturbances carry energy along with them, transferring it from one place to another. When we think of waves, we often picture the familiar sight of ripples on the surface of water, but waves can take many different forms and occur in various mediums. One key characteristic of waves is their ability to transfer energy without significantly moving the medium itself. This is known as wave motion, where the particles of the medium oscillate around their equilibrium positions as the wave passes through. For example, in the case of sound waves traveling through air, the air molecules vibrate back and forth in the direction of the wave, transmitting sound energy from the source to our ears. Another important aspect of waves is their ability to exhibit different properties d...
